Thanx BigT (all texans are big? )
In fact the wood grain is so tight that the polishing is done quite easily, after a 400 sanding. The little koru was working on the wood butt, that's also the reason of thin grain.

Yesterday,I've try for pearl inlay, I think I've the solution...
Advise are welcome...

Thanx Benz, For pearl inlay I cheat a little...In fact I proceed by double hole and I wedge a tiny cylinder of wood in the center...
I've find some old carving, made maybe in 2004, before big work in our house and birth of our daughters. It was ten or twelve but I've gave all the pieces at friends or old coworkers.There I keep two, not finished (maybe the worst):

I'm glad to refind them.

Thanx for LOL reply Big T!!!
Today I keep my baby, but I can't stop carve even in the kitchen! Am I severely affected??
the advantage is that I can eat chips!!

WOW boy, you're an addict now ! I think that addicted to tiki is the best addiction

Everything's cool on your update my friend.
The old tikis are nice, the carrots are great, the hei tikis become fantastic and the Koru is simply unbelievable: the edge you marked makes it totally.
Did you try potatoes ? (I tried ) Potatoes seem to have rings like wood.

Thanks for the link, one of the pictures will help me in carving a bigger marquesan I have begun a while back.
